send email on positive hit

[cjyoung]

after creating functionality to automatically re-search based on an interval, add functionality to send an email to yourself when a time becomes available

potential solution:

• box for gmail login/pass
• use gmail for smtp and look at other offerings later (like config smtp/imap)
• ask users if they'd like to save username/pass (encrypt with secret, salt with a unique machine code, so if settings are copied to another computer, they won't be able to be decrypted)
